FAQs on JavaFX Java GUI Tutorial - 20 - Adding and Deleting TableView Rows Video Lecture - JavaFX Java GUI: Learn to build Powerful Applications - Front-End Programming

1. How do I add a row to a TableView in JavaFX?
Ans. To add a row to a TableView in JavaFX, you can create a new instance of the data model class that represents the data in the row, and then add that instance to the TableView's data list. For example, if you have a TableView of Person objects, you can add a new person by creating a new Person object and adding it to the TableView's ObservableList<Person> data list.
2. How can I delete a row from a TableView in JavaFX?
Ans. To delete a row from a TableView in JavaFX, you can get the selected row using the TableView's getSelectionModel() method, and then remove that row from the TableView's data list. For example, if you have a TableView of Person objects, you can delete the selected person by getting the selected row and removing the corresponding Person object from the TableView's data list.
3. Can I add or delete rows dynamically in a TableView in JavaFX?
Ans. Yes, you can add or delete rows dynamically in a TableView in JavaFX. You can use the same approach mentioned earlier to add or delete rows based on user actions or any other events. By manipulating the TableView's data list, you can easily update the rows displayed in the TableView.
4. How do I update the TableView after adding or deleting rows in JavaFX?
Ans. After adding or deleting rows in a TableView in JavaFX, you can update the TableView by calling the TableView's refresh() method. This method will refresh the TableView's view and display any changes made to the TableView's data list.
5. Can I add or delete multiple rows at once in a TableView in JavaFX?
Ans. Yes, you can add or delete multiple rows at once in a TableView in JavaFX. To add multiple rows, you can create a list of data model objects representing the rows and add them to the TableView's data list. To delete multiple rows, you can get the selected rows using the TableView's getSelectionModel() method and remove the corresponding objects from the TableView's data list. Remember to call the refresh() method to update the TableView after adding or deleting multiple rows.
